Technical field
The present invention relates to a kind of tail gas draw-out device, particularly the calcium oxide aquation tail gas draw-out device in a kind of nano-calcium carbonate production.
Background technology
In nano-calcium carbonate is produced, calcium oxide and water course of reaction are exothermic reactions, and exothermic heat of reaction can produce steam, and conventional method is to utilize chimney to bleed, and the steam of generation is entered in atmosphere.But owing to containing calcium oxide dust in tail gas steam, easily cause chimney blocked, make steam tail gas accumulate in workshop inside.This steam tail gas not only pollutes atmosphere, also affects shop personnel's health simultaneously.Prior art has the exhaust mode that adopts blower fan to carry out forced draft, but fan blade easily adheres to calcium oxide dust contained in tail gas steam, caused the dynamic balancing of fan blade to destroy, fan trouble rate takes place frequently, and the extraction of calcium oxide aquation tail gas cannot normally be moved.
Summary of the invention
The invention provides a kind of nano-calcium carbonate calcium oxide aquation tail gas draw-out device in producing, not only reclaimed the heat of tail gas, and solved existing calcium oxide and react the problem that the extraction of produced calcium oxide aquation tail gas cannot normally move with water.
The present invention solves above technical problem by the following technical programs:
Calcium oxide aquation tail gas draw-out device in a kind of nano-calcium carbonate production, comprise condenser tank, condenser Guan top exhaust outlet is communicated with the input port of air-introduced machine by air-introduced machine exhaust tube, on the delivery outlet of air-introduced machine, be provided with air-introduced machine blast pipe, in the tank skin lower end of condenser tank, be provided with calcium oxide aquation tail gas input port, in condenser tank, along tank body central axis, be provided with median septum, median septum is separated into dust spray district and the roundabout discharge area of tail gas by the middle lower inner cavity in condenser tank, calcium oxide aquation tail gas input port is arranged on the tank skin in dust spray district, on the tank skin on the top in dust spray district, be provided with shower water water inlet, on shower water water inlet, be provided with the shower with spray head, in the middle and upper part of the roundabout discharge area of tail gas, be provided with gear gas swash plate, between gear gas swash plate and median septum, be provided with tail gas circuitous channel, condenser Guan top exhaust outlet is arranged on the roof of the condensation gas tank on the roundabout discharge area of tail gas.
On the top of the roundabout discharge area of tail gas, be respectively arranged with lower dovetail fin back shaft and upper dovetail fin back shaft, on lower dovetail fin back shaft, compartment of terrain is provided with lower dovetail fin, on upper dovetail fin back shaft, compartment of terrain is provided with dovetail fin, and lower dovetail fin and upper dovetail fin are to arrange in the other direction.
The present invention adds knockdown condensation and steam-water separator before air-introduced machine, tail gas is first introduced to condenser tank, in condenser tank, adopt spiral nozzle to spray vaporific cooling water, tail gas is baffling in condenser tank, extended gas-liquid contact time, cooled tail gas carries out that gas-water separation is laggard enters blower fan, by chimney, is discharged.The water inlet of sending into ashing melting machine with the condensed water after steam heat-exchanging recycles.
The invention solves nano-calcium carbonate produces in digestion operation; lime reacts spilling in air shopwork environment is caused to dysgenic problem containing the steam difficulty of dust of producing in link in ashing melting machine with water; preferably this part of tail vapour is processed; improve environment; reclaim heat; save the energy, protected environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
